FAN CONSTRUCTION.

$PECIFICATION forming part of Letters Patent No. 741,107, dated October13, 1903.

Application filed April so, 1903. Seriall ic.156,057. (NomodelJ T ctZZwhom it Duty concern:

Be it known that I, WORLEY WALDEN BURNES, a citizen of the UnitedStates, residing at McCoy, iu the county of Kaufman and State of Texas,have invented certain new and useful Improvements in Fan Construction;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled [O intheart to which it appertains to make and use the same.

My invention relates to fan construction; and it consists of certainnovel features of combination and construction of parts, the

preferred form whereof will be hereinafter clearly set forth The primeobject of my inventionfamong others, is to provide a fan which. shallconsist of a few actuating parts, comprising a spring-motor which may beeasily and quickly wound and when wound provides power for many hours.

A further object of my invention is to provide simple though reliablyefficient means 2 5 for adjusting the blades of the fan whereby they maybe disposed in any preferred position and deemed productive of the best"resuits.

Another' object is to provide means for. readily adjusting the height ofthe fan from the table or desk.

Other objects and advantages will be hereinafter made clearly apparent,reference being had to the accompanying drawings, which 35 are made apart of this application, and in which- Figure 1 shows a side elevationof my invention applied to use. Fig. 2 is a detail view showing meansfor readily adjusting the blades of the fan proper whereby they may bedisposed at any desired angle. Fig. 3 shows means for adjusting theheight of the fan from the ceiling. Fig. 4.- is a sectional view of themotor, showing the preferred arrangement of the train of gears andactuating spring therefor. Fig. 5 is a top plan view of the fan-bladesand accompanying parts. Fig. 6 is the cross-bar to which the fan-bladesare secured. Figs. 7 and 8 show means for 50 adjusting the relativeposition of the fanblades.

Referring to the various details of my invention and cooperatingaccessories, numerals will be employed, the same numeral applying to asimilar part throughout the several views.

Referring to the numerals on the drawings,

1 shows the casing of any preferred size and shape, designed as ahousing for the motor, which consists of the actuating-spring 2,operatively connected with the master-Wheel 3, which latter is in meshwith the power-communicating wheel 4, which is journaled on the shaft 5,having suitable bearings in the brackets or cross-bars 6 and 7, whichlatter are connected with each other by means of the depending arm 8 orthe equivalent thereof. To the lower end of the shaft 5 I secure thegear-wheel 9, which is in mesh with the gear 10, carried by the upperend of the shaft 11, to the lower end of which is secured thefan-carrying arms or bar 12, which is provided centrally with a squareaperture 13, designed to receive the similarly-shaped end of the shaft11, a suitable set-screw 14 being provided to insure a union of saidparts.

It will be observed that the master-wheel 3 is mounted, as is common,upon ashaft 15, the outer end of which'receives the windingkey 16, whilea suitable pawl and ratchet 17 is also provided to hold the master-wheelagainst reverse rotation while being wound, as is common.

The fan-blades 18 may be adjusted by means of the toothed bar 19,whichis provided with the longitudinal slot 20, which is adapted to receivethe end of the bolt 21, which at the point where it passes through saidslot is square in cross-section. The bolt 21 is also squared, so as tobe received by the square 0 aperture 22, formed in the outer end of thearm 12, so as to insure'that the plate 19 will be held in a truevertical position with its cogs or teeth pointing outward and adapted tomesh with the segmental toothed bracket 23. g5

The segmental bracket 23 is provided with an arm 24, having apertures 25and 26. The aperture 26 is adapted to receive the bolt 27 which passesthrough a registering aperture provided in the fan or blade 18, whilethe ap- 10o erture 25 is'intendedtoreceive the bolt 28, which passesthrough registering apertures in the inner end of the fan or blade andalso through the aperture 29 in the extreme outer end of the arm 12, andit is therefore obvious that the bolt 28 forms a pivot-point by means ofwhich the outer end of the fan or blade may be raised or lowered throughthe mediation of the rack-bar 19 and the segmental bracket 23. It istherefore clearly obvious that by loosening the nut upon the bolt 21 therackbar 19'may be raised or lowered, as desired, which will incidentallylower or raise, respectively, the outer end of the blade 18, therebyenabling a proper adjustment of said blade to be quickly etfected,whenthe nut upon the bolt 21 may be tightened, thus locking the blade in anadjusted position.

To the upper side of the housing 1 I secure the tubular extension orelongated socket 33, which is adapted to receive the lower end of theshaft 34, said shaft being secured in said socket, as by the set-screw35, thus enabling the motor and fan carried thereby to be raised orlowered to any desired point. It will thus be seen that I have providedsimple though effective means for adjusting and securing the fan-bladesin any desired position, and While I have described the preferredcombination and construction of the various parts deemed necessary inmaterializing my invention I desire to comprehend such substantialequivalents and substitutes as may be considered as fairly fallingwithin the scope of my invention.

Believing that the advantages and manner of using my improved fan havethus been made clearly apparent, further description is ward from thehousing of the motor, adapted to adjustably receive the end of adepending shaft, in combination with a driving-shaft 1 l connected withsaid motor and extending downward below the same; a cross-bar or pair ofarms 12 connected to the lower end of said shaft; and each arm carryinga rack-bar adjustably connected to its end; a pair of fanblades eachhaving at its inner end a segmental toothed bracket 33 adapted to meshwith one of said rack-bars and means to change the relative position ofsaid parts whereby the fan-blades will be adjusted and secured at anydesired angle all combined substantially as specified and for thepurpose set forth.

In testimony whereof I affix my signature in presence of two witnesses.I

WVORLEY WALDEN BURNES.
